JOB S. CRANE, OF NEWARK, NEW JERSEY, ASSIGNOB TO THOMAS W. LANGSTROTH,OF SAME PLACE.

IMPRQVEMENT IN GONG-BELLS.

Specification forming part of Letters Patent No. 213,176, dated March11, 1879; application filed January 28, 1879. i

To all whom it may concern:

Be it known that I, Jon S. CRANE, of Newark, in the county of Essex andState of New Jersey, have invented certain new and useful Improvementsin Gong-Bells; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being hadto the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

The object of this invention is to improve that class of bells used assignals upon cars, steamboats, and in many other places where audiblesignals are needed, by simplifying their construction, and thuslessening their cost, while the durability and efficiency of theinstrument is increased; and the invention consists in certain detailsof construction, which will be hereinafter fully described, and thenspecifically pointed out in the claims.

Figure 1 of the drawings is a plan of the base-plate, which carries thebell and its operative mechanism, the bell-being removed so as to showthe devices by which the hammer Fig. 2 is a transverse section on theline no a: of Fig. 1, and shows the relative positions of the bell andbase-plate. Fig.3 is a section through the line 1 3 Fig. 1.

A represents the metallic base-plate, which may be cast with openings ato reduce its weight, and is further pierced with holes bfor thereception of the screws by which it is attached to the car or otherstructure on which it is to be used. It is also provided with loops 0and 0, cast with the plate, which act as guides to the draw-bar B. Thisdraw-bar is provided with a ring at its outer end, to which the cord orwire by which the bell is operated is attached, and projecting from iton opposite sides is the stop I), whichlimits its movement in onedirection, and the stop-pawl d, which not only limits the movement inthe opposite direction, but by its action upon the projection d of thehammer 0 draws back the latter, causing it to strike the bell whenever apull is made upon the draw-bar. This hammer is preferably cast in onepiece of metal with its handle, thus reducing its cost, and is pivotedupon the stud e, which projects from the base-plate by an open bearing,and is prevented from leaving the stud 6 when the hammer is moved by thepin 0, inserted into the plate A at such a distance as to allow freemovement of the hammer upon the stud.

Another short stud, f, is cast upon or otherwise secured to the plate A,in the rear of the hammer-handle, and prevents the latter from beingthrown too far back by a sudden pull or jerk of the draw-bar, while thestud f prevents the hammer from touching the bell when in a state ofrest; but when the hammer is drawn back and then suddenly let go theelasticity of its handle allows the momentum to carry it on and intoforcible contact with the bell. A curved projection, g, is formed on thehammer-handle, to which one end of the coiledwire spring h is secured,the other end of the spring being attached to the spur 'i, cast upon orotherwise secured to the base-plate A. This spring serves to retract thehammer after it has been drawn out by the action of the drawbar upon theprojection d, causing it to strike the bell D. This bell is supportedupon the pillar E, which rises from and is secured to the base-plate Aby riveting or other suitable means.

In order to retract the draw-bar after it has been drawn out, a spring,h, is attached to the projection is upon the draw-bar at one end, theother being secured to the spur 1", projecting from the base-plate.

It will be observed that the loop 0 is open at one side, while the loop0 is much wider than the draw-bar, thus allowing the latter to oscillateor play edgewise to a considerable extent.

This play allows the draw-bar to be retracted by the spring h after ithas been drawn outward in striking the bell, as the inclined edge of thestop-pawl d, striking the projection d, oscillates or throws the bar toone side, thus allowing the stop-pawl to pass the projection d upon thehammer-handle, after which the draw-bar is drawn to the side of the loop0 by the action of the spring h, so as to place the stop-pawl within andopposite the projection d in readiness for another blow of the hammer.

This arrangement greatly simplifies the construction of the apparatus,reducing the number ofparts used, and leaving them strong and capable ofenduring long use without breakage or derangement of the working parts.

Havin g thus described myinvention, I claim as new, and desire to secureby Letters Patcut, the following: 1

1. The bed-plate A, provided with the open and elongated loops 0 and c,in combination with the oscillating draw-bar B, having upon one side thestop I) and upon its opposite side the projection 7c and stop pawl d,the latter being arranged to strike against the projection d inactuating the hammer O, substantially as set forth.
